Highlights and Novelties

1. This paper discusses about the new design technique for next generation devices.

2. It also discusses about the scope of antenna design using DRA because it has many advantages such as small size, light weight, low dissipation loss, high radiation efficiency and ease of excitation as well as wider impedance bandwidth as compared to micro-strip antenna.

3. Design of multi-functional antenna will reduce the overall design aspect of the device.

Manuscript Abstract
The tremendous growth in wireless communication resulted exponential increase in the mobile phones density and their functionalities, this was pushed further with the advent of the Internet of Things (IoT). Multi frequency band support made them to cover important standards like: GSM (1800MHz & 1900MHz), UMTS (2100MHz), Bluetooth & Wi-Fi (2.4GHz) and LTE system (2.3GHz, 2.5GHz, and 2.6GHz), which necessitated design of ultra wide band compact antennas. Moreover the smaller mobile phones with enhanced services increased the user ability to use the mobile phone for different applications with good performance across the world for multiple functionalities. An up-to-date literature overview is presented here to make dielectric resonator antennas (DRAs) as potential candidates for those smart wireless devices operating at millimeter waves and beyond, we also examining current trends and future scope. Considering space limitation, port-to-port isolation or mutual effects of other elements, the conventional solution of using two or more antennas to realize multi-functionality and/or diversity schemes may not be possible with ever reducing wireless portable devices. So Micro-strip patches and dielectric resonators (DRs) are two low-profile variants surfaced for modern microwave and millimeter wave antennas. Among them two predominate solutions currently used in compact mobile communication devices are multi-ports printed diversity antenna and planar inverted-F antenna (PIFA) to achieve multi-functionality and diversity schemes. They are single antenna structures, which support several functions with low mutual power coupling between different ports. Both these antennas designs have advantages of compact size, low fabrication cost and low profile as desired but they usually suffer from their complicated structure, large size, relatively low gain compared to other conventional antennas, on the other hand dielectric resonator antennas (DRAs) are promising to overcome most of the limitations.
